Little Brown Caddis (Lepidostoma pluviale)

This little caddisfly is often overlooked because it usually does not show up in
quantities that overshadow the more popular spotted sedge. It can be found in large
numbers and the trout will eat them just as readily as the
hydrosyche species. The
females are a hook size 18 and the male a 20. It is a cased caddis that hatches in the
evenings over a long period of time.
You will find these caddisflies just about all summer long on most all the streams in
Yellowstone National Park. Although they hatch mostly in the evenings, trout can be
taken on imitations of the pupae late in the afternoon and early evening. They hatch
out in the stream by swimming to the surface. The adults ride the surface a few
seconds before flying away. Trout can also be taken on a dry imitation of the adult
during the hatch.
Egg laying usually starts in the late afternoon and continues into the evening providing
another dry fly opportunity. The female adults actually ride the surface of the water for
a short period of time when depositing their eggs.
